Quran State Affairs SOVEREIGNTY

The difference between an Islamic State and a secular state is that in an Islamic State, affairs are conducted within limits laid down by the Quran. Nobody has the right to transgress these limits; in other words, the right to rule belongs to Allah Almighty alone. It is said in Surah Yusuf (12:40)
"Remember! The command is for none but Allah"
(18:26) "Nor does He share His Command with any one whosoever". If the right to rule is bestowed upon any person or a group of persons, whatever be their name, that shall amount to ascribing partners with Allah. No one, how highly placed he may be, even as high as a Messenger of Allahe, has the right to make people subservient to himself. Surah Aal-e-Imran says: (3:78) "It is not for any human being unto whom Allah Almighty has given the Book and wisdom and the Divine Message, that he should afterwards have said unto mankind, 'Obey me instead of Allah'. He should rather say, 'You should be amongst those who are subservient to Allah Almighty by following His Book which you study and teach others'." Be it clear, that it is the Messenger of Allah Almighty who first receives the Book, then he delivers it to others. That is how the Book of Allah Almighty reaches the common man. The Quran was initially revealed to the 'Nabi'e. Later it became inherited by Muslim Ummah. It is said in Surah Faatir (35:32)
"Then We have given the Book for inheritance to such of our servants as We have chosen (It means the Muslim Ummah)". The duty of the Ummah is to establish an Order according to this Book; thus an Islamic State is an agency that enforces the divine command. On the contrary, the system of government in which the right of law-making is exercised by human beings, is a secular regime, whatever its shape may be. That is the line of demarcation between infidelity and Islam, Kufar and Islam. Allah Almighty ordains: (5:44)
"Those who do not establish a rule according to what Allah Almighty has revealed, are non-believers."
